Excavator Tilt Coupler & Actuator Seal Kit Cross-Reference Guide

Use this guide to identify the correct hydraulic seal and bearing kit for your excavator's tilt coupler or tilt hitch actuator. Kits are listed by brand, tonnage class and the machine/attachment model numbers they fit — including PTE, Attach2 Heli-Tilt (HT & HTR Series) and Doherty D-Lock tilt couplers.

Not sure which kit you need? Check the tag on your actuator housing for a model or part number and match it against the tables below, or contact our team with your machine make and model and we'll confirm the right kit.

PTE & Attach2 Heli-Tilt Actuator Seal Kits

Heli-Tilt actuators use a helical (screw-type) hydraulic actuator instead of a full tilt rotator, giving tilt movement without extra tilt hoses. Kits come in two designs: bearingless (uses an external wiper seal) and with internal bearings (no external wiper seal) — check your actuator design before ordering.

PTE Actuator Seal Kits

Genuine-spec replacement seal and bearing kits for PTE brand tilt coupler actuators, covering 2 to 35 tonne excavator classes. Available in bearingless (external wiper seal) and internal-bearing designs.
